Contracts and modes
The campaign is only the beginning. Contracts and modes change the rules of a run, the risk and the rewards. Here is how they work and which one to pick depending on what you are after.

What a contract is
Before setting off on a mission you can choose a contract. A contract does not change the world you face, but it changes the rules: how much health you recover, how tough enemies are, how many lives you have and what you get at the end.
The idea is simple: the more risk you accept, the more interesting the reward. But a contract too hard for your level only wastes your time, so it pays to climb one step at a time.
The four contracts
These are the contracts in the current build, from the easiest to the most demanding:

- Normal mission: the standard rules. The right contract for learning a world and clearing it the first time.
- Silence contract: removes all healing and makes enemies tougher, but pays more coins. Ideal when you know a world well and want to grow your gear.
- Storm contract: adds pressure and projectiles, and offers elemental materials in return.
- Master contract: more complex fights and a single life, with the best odds of finding rare items.
Which contract to choose
The Silence contract is the most deceptive: with no healing, every hit you take stays for the whole run. It only works if you can already avoid almost every attack in the world you are playing. A good test is clearing that world on a Normal mission without using the angels’ healing.
The Master contract, with a single life, is meant for players hunting rare items who know the bosses by heart. Before trying it, it is worth having a ninja with high permanent levels and a well-upgraded weapon.
The modes
As your account level rises, new modes open up, each with its own purpose:
- Training Dojo: try ninja and gear on training dummies. No rewards or progress, but it does not use up a run.
- Daily Challenge: a fixed setup that changes every day. Everyone starts from the same conditions, so only your play counts.
- Boss Rush: a string of bosses with limited healing. The best way to practise reading their strongest moves.
- Endless mode: rooms without end, with the goal of beating your record.
A suggested path
If you want an order to follow, this one works for most players:
- Clear the Bamboo Forest on a Normal mission.
- Use the Dojo to try every new weapon or ninja.
- Play the Daily Challenge every day: it is short and trains adaptation.
- Move to the Silence contract on the worlds you know best.
- Keep Boss Rush and the Master contract for when bosses have no secrets left.
